The Low-Mass End of the IMF in Chamaeleon I
We have compared the low mass and brown dwarf samples of Cha I deduced by optical and infrared techniques. We conclude that optical methods tend to lead to an underestimation of the number of brown dwarfs at least by 15% but possibly by 40 %. Highly complete samples can be constructed by combining optical and mid-infrared samples.
